Description

Multifunctional fast black dyeing gel and preparation method thereof

Technical Field

The application relates to the technical field of hair dyeing cosmetics, in particular to multifunctional fast black dyeing gel and a preparation method thereof.

Background

The hair dyes are various, and include temporary hair dyes, semi-permanent hair dyes and permanent hair dyes according to the color fixation degree. The permanent hair dye has wide application range due to high color fastness and high dyeing durability. The permanent hair dye is an oxidation type hair dye, which enters a hair sebum layer through a micromolecule intermediate such as p-phenylenediamine, resorcinol and the like and a coupling agent, and then is subjected to condensation reaction under the action of an oxidizing agent to generate larger dye molecules, so that the dye molecules are enclosed in hair fibers, the effects of changing hair color and fixing color are achieved, and the hair dye has longer durability.

The hair dye generally comprises a hair dye cream and a color developing agent which are separately prepared and stored, and when the hair dye is used, the hair dye is mixed according to a certain proportion and then acts on hair. However, most hair dyeing pastes are emulsified systems, the blackening speed of the hair dyeing materials is high, white hair cannot be judged whether to be dyed completely, and the hair is easy to dye black and cannot be cleaned easily.

In order to solve the problem that the hair dye cream is easy to be blackened quickly, the Chinese patent application with the publication number of CN1421188A discloses a hair dye composition, which achieves the effects of delaying the oxidation of compounds in the composition and not influencing the hair dyeing by adding 0.6-20 mass percent of phenyl methyl pyrazolone. However, with the release and requirements of relevant standards, for example, those specified in the technical specifications for cosmetic safety (2015 edition): phenylmethylpyrazolinone is one of the hair dyes for cosmetic use, and the maximum usage amount of the phenylmethylpyrazolinone in the hair dye product is 0.25%. If the hair dye paste and the developer are mixed according to the general dosage ratio of 1:1, the hair dye after mixing is estimated by the density of 1g/mL, namely, the dosage of the phenyl methyl pyrazolone in the hair dye paste should not exceed 0.5 percent by mass. When the using amount of the phenyl methyl pyrazolone is less than 0.5 mass percent, the hair dye is still easily and rapidly oxidized and blackened in a short time, so that macromolecular dyeing substances generated by the reaction cannot enter hair cortex, only a small amount of micromolecular dye intermediate and coupling agent permeate into the hair cortex, and the dyeing effect is poor, and whether the coloring is finished or not cannot be judged.

Particularly, the coloring time of the black-dyed gel prepared by the formula components provided in the embodiment 3 is 8min, and the color change time of the black-dyed gel is 45min, which is the best embodiment.

Comparing the test results of the example 3 with those of the comparative examples 1 and 2, the coloring time of the products obtained in the comparative examples 1 and 2 is 12min and 14min respectively, the scalp has a blackening phenomenon, the washing fastness is 3 grades and 2 grades respectively, and the rinsing fastness is 3 grades and 2 grades respectively. It can be seen that the component A only adopts polyhydroxy phenol or phenyl methyl pyrazolone as an oxidation retarder, the coloring time of the prepared black dyeing gel is prolonged, the body blackening time is obviously shortened, the color change is quicker, the black scalp is easy to dye, and the washing fastness and the rinsing fastness are also reduced.
